What did Dalton's atomic theory teach?
Apex

Dalton's atomic theory taught that all matter composed of atoms (inseparable and cannot be destroyed).

Explanation:

Dalton's atomic theory, the initiative comprehensive approach to explain all matter based on atoms and its properties. He proposed this theory based on the law of mass conservation and constant composition law. The importance of Dalton's atomic theory are:

Everything consists of atoms, which are inseparable elements of matter and cannot be impaired. All element's atoms are identical. Atoms of different elements differ in their sizes and masses. Compounds are created by simply bonding atoms and creating complex atoms (molecules).

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

i believe the answer is three water molecules
